In order to make those skilled in the art person understand the present invention program better; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment only is the embodiment of the present invention's part, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the present invention's protection.

Embodiment one

An embodiment of conference control method of the present invention; Can comprise: receive the first area speaking request; Wherein, the first area speaking request carries first meeting-place sign and first area sign, and first meeting-place identifies pairing meeting-place and comprises a plurality of zones; First meeting-place identifies pairing meeting-place and belongs to first meeting, and the first area is designated the area identification that said first meeting-place identifies the request floor zone in the pairing meeting-place; If confirm to allow the request floor zone speech of first area sign correspondence, then trigger and in first meeting, remove the regional corresponding speech video of meeting-place terminal broadcast this application speech that first meeting-place identifies pairing meeting other at least one meeting-place outside the venue.

Referring to Fig. 2, concrete steps can comprise:

210, conference control equipment receives the first area speaking request;

Wherein, above-mentioned conference control equipment possibly be the conference control equipment (for example meeting control and management platform or MCU etc.) of network side, also possibly be the conference control equipment (the for example terminal, meeting-place of the Chair site of meeting) of end side.

Under a kind of application scenarios; Carry out in the process in meeting; If a certain zone in certain meeting-place under it (for ease of describing, can be referred to as first meeting-place, the meeting-place sign in this meeting-place can be referred to as first meeting-place sign) is (for ease of describing; Can this zone be called the first area) needs request speech; Then for example the terminal, meeting-place in this meeting-place (for ease of describing, can be referred to as terminal, first meeting-place) can be used as speech application equipment, to network side conference control equipment (for example being meeting control and management platform or MCU etc.) sending zone speaking request (for ease of describing; Be referred to as the first area speaking request), this speaking request portability first meeting-place, first area sign and first area sign (first area is designated the area identification of said first area).

Wherein, this first meeting-place can comprise a plurality of zones, and first meeting-place belongs to first meeting, and first meeting also comprises other one or more meeting-place.Be appreciated that this first area sign can be can be with distinguishing any sign that comes with other zone in this meeting-place in the zone.

Special; Speech also can not real-time applying for; But speech application in the statistical time range is carried out in the lump; If in a statistical time range (for example 30 seconds or 60 seconds etc.), first meeting-place has a plurality of zones to need request floors, and speech application equipment (like terminal, first meeting-place) also can obtain the area identification in a plurality of request floors zone; Generate and send the regional speaking request of the area identification that carries first meeting-place sign and this a plurality of request floors zone, conference control equipment then can receive this zone speaking request.

In practical application; The meeting-place sign in area identification and corresponding meeting-place can be two independently signs, also unites two into one, for example; The meeting-place identification information that comprises corresponding meeting-place in the area identification; Be about to the part of meeting-place sign, perhaps can derive the meeting-place sign in corresponding meeting-place, under this scene through area identification as area identification; In fact the zone speaking request possibly a carrier area identify, but still can think that this zone speaking request carries area identification and the meeting-place sign that unites two into one.

Need to prove; The network side conference control equipment here is that network side can be managed and the equipment of handling the relevant signaling of meeting; It for example can be meeting control and management platform (if existence); But signalings such as meeting control and management platform management area speaking request, meeting-place speaking request, and control medium processing device or MCU carry out processing and the broadcasting of audio-video frequency media stream etc.In addition; In the networking structure of not disposing meeting control and management platform; The network side conference control equipment then can be MCU (the MCU here can think to have the function of all or part of meeting control and management platform), MCU can be autonomous or with terminal, the meeting-place cooperation of the Chair site (if existence) of meeting, signalings such as management area speaking request, meeting-place speaking request; And can receive audio-video frequency media stream from the terminal, meeting-place; Carry out processing and the broadcasting of audio-video frequency media stream etc., certainly, the network side conference control equipment also can be the equipment of the similar functions of other networking.The terminal, meeting-place of the Chair site in the meeting (if existence) then can be regarded end side conference control equipment (the Chair site terminal can be called for short in the terminal, meeting-place of Chair site) as.It is understandable that; The user both can directly pass through each terminal, meeting-place and send the meeting control command to the network side conference control equipment; Also possibly be to pass through other instrument the meeting control command is sent to the terminal, meeting-place, transmit this meeting control command by the terminal, meeting-place and give the network side conference control equipment with corresponding authority.In addition, under another kind of scene, the meeting control commands such as regional speaking request in corresponding each meeting-place also possibly passed through miscellaneous equipment and directly send to the network side conference control equipment, and need not transmit through the terminal, meeting-place.Such as at internet protocol multimedia subsystem (IMS; IP Multimedia Subsystem) under the network, a kind of Conference server possibly supported several clients, and each meeting-place can sign in to this client through IE browser client input meeting-place number; Carry out meeting control then; Such as initiating application, apply to become chairman etc., speaking request can directly be transmitted to the Chair site terminal through Conference server in this case.That is to say, if conference control equipment is the conference control equipment of network side, its maybe be from receiving area, terminal, meeting-place meeting control command such as speaking request, also maybe be from the miscellaneous equipment receiving area meeting control command such as speaking request.If conference control equipment is the end side conference control equipment, its maybe be from network side conference control equipment receiving area meeting control command such as speaking request, also maybe be from the miscellaneous equipment receiving area meeting control command such as speaking request.

220, conference control equipment then triggers and in first meeting, removes the regional corresponding speech video of meeting-place terminal broadcast this application speech that first meeting-place identifies pairing meeting other at least one meeting-place outside the venue if confirm to allow the request floor zone speech of above-mentioned first area sign correspondence.

Wherein, If above-mentioned conference control equipment is the network side conference control equipment; And this network side conference control equipment does not for example have the equipment of medium processing capacity for meeting control and management platform etc.; Then it can be when confirm allowing the speech of above-mentioned request floor zone, triggers the equipment that for example medium processing device or MCU etc. have the medium processing capacity and in first meeting, remove the corresponding speech video in terminal broadcast this application speech zone, meeting-place that first meeting-place identifies pairing meeting other at least one meeting-place outside the venue; The equipment that if above-mentioned conference control equipment is MCU etc. has the medium processing capacity; Then it can trigger and self in first meeting, remove the corresponding speech video in terminal broadcast this application speech zone, meeting-place that first meeting-place identifies pairing meeting other at least one meeting-place outside the venue when confirm to allow the speech of above-mentioned request floor zone.If above-mentioned conference control equipment is end side conference control equipment (for example Chair site terminal); Then it can be when confirming to allow the speech of above-mentioned request floor zone; Trigger the equipment that medium processing device or the MCU etc. of (specifically can be directly or pass through meeting control and management platform for example etc. and trigger indirectly) network side have the medium processing capacity, in first meeting, remove the speech video that first meeting-place identifies terminal broadcast this application speech zone, meeting-place correspondence in pairing meeting other at least one meeting-place outside the venue.Certainly; Conference control equipment allows above-mentioned first area to identify the regional speech of corresponding request floor as if confirming, also can trigger to comprise that in first meeting first meeting-place identifies the regional corresponding speech video of meeting-place terminal broadcast this application speech in a plurality of meeting-place in pairing meeting-place.

Under a kind of application scenarios; Network side conference control equipment or end side conference control equipment are if confirm to allow the request floor zone speech of this first area sign correspondence; Can also trigger to first meeting and remove the audio frequency that first meeting-place identifies meeting-place terminal broadcast first meeting-place or the above-mentioned request floor zone in pairing meeting other at least one meeting-place outside the venue; Certainly; Network side conference control equipment or end side conference control equipment also can or preset tactful audio frequency to this application speech zone and close the sound processing according to instruction, promptly do not broadcast the audio frequency in the request floor zone of first meeting-place or this first area sign correspondence to other meeting-place.

In practical application; Network side conference control equipment or end side conference control equipment confirm that it can be diversified allowing the mode of request floor zone speech; For example; The network side conference control equipment can be transmitted the first area speaking request to the terminal, meeting-place of the Chair site of first meeting (if existence); If receive the instruction in the request floor zone of this first area sign correspondence of roll-call broadcasting of sending at the terminal, meeting-place of this Chair site, then confirm to allow the request floor zone speech of this first area sign correspondence; Perhaps, network side conference control equipment or end side conference control equipment also can or preset the request floor zone speech that strategy confirms to allow this first area sign correspondence according to user instruction.

Further; In the process in the corresponding request floor zone of broadcasting first area sign of calling the roll; Network side conference control equipment or end side conference control equipment also can receive the regional speaking request signalings such as (being referred to as the second area speaking request here) in other meeting-place (second meeting-place for example, the meeting-place sign in this second meeting-place can be referred to as second meeting-place sign) of first meeting, wherein; Second meeting-place also can comprise one or more zones, and second meeting-place belongs to first meeting; This second area speaking request is carried second meeting-place sign and second area sign, and second area is designated the area identification in the request floor zone in second meeting-place; If confirm to allow the request floor zone speech of second area sign correspondence; Then can trigger in first meeting and to remove second meeting-place and identify the corresponding speech video in request floor zone in meeting-place terminal broadcast second meeting-place in pairing meeting other at least one meeting-place outside the venue, to realize supporting the program request of a plurality of speech application objects.Wherein, Can carry out the broadcasting of the audio-video frequency media stream in a plurality of speech applications zone simultaneously; For example; Can carry out simultaneously; In first meeting, remove second meeting-place and identify the corresponding speech video in request floor zone in meeting-place terminal broadcast second meeting-place in pairing meeting other at least one meeting-place outside the venue, and in first meeting, remove second meeting-place and identify pairing the meeting corresponding speech audio frequency in the request floor zone in meeting-place terminal broadcast second meeting-place in other at least one meeting-place or the audio frequency in this meeting-place outside the venue.And the terminal, meeting-place in each meeting-place can be all or optionally show the speech video that receives in first meeting.

Further, network side conference control equipment or end side conference control equipment can also generate and safeguard speech application tabulation, so that speech application object is effectively managed.For example; After receiving the first area speaking request; Network side conference control equipment or end side conference control equipment can add the corresponding record of first area speaking request in the speech application tabulation of first meeting; After receiving the second area speaking request; Can in the speech application tabulation of first meeting, add the corresponding record of second area speaking request, for example can in speech application tabulation, add the information such as area identification in request floor zone, so that the follow-up corresponding request floor zone of area identification of from this speech application tabulation, selecting to allow speech.

In practical application; At least 1 video camera of correspondence (perhaps one road motion video) can be distinguished in each zone in the meeting-place; And video that should the zone has this at least one video camera to take to catch, and perhaps, a plurality of zones in the meeting-place can a corresponding wide-angle imaging machine (this wide-angle imaging machine can be taken whole meeting-place); Can carry out the image cutting according to area dividing by the equipment that terminal, meeting-place or MCU etc. have a medium processing capacity; Then corresponding cutting image of speech video that certain request floor zone is corresponding, MCU etc. have the equipment of medium processing capacity can be broadcasted cutting image, perhaps splices broadcasting to a plurality of cutting images.

In practical application; No matter network side conference control equipment or end side conference control equipment are selected one or select the broadcasting of calling the roll of a plurality of request floors zone simultaneously, the request floor area relative of the broadcasting of all can clearly the being called the roll display position of video on the screen in each meeting-place of making a speech.For instance, the default acquiescence of each speech area relative speech video shows (the corresponding multi-screen of the speech video meeting-place that the screen 1 of speech video correspondence in each meeting-place of catching such as the video camera 1 in certain meeting-place shows, send at the terminal, meeting-place in single screen meeting-place main shields or all screens show etc. simultaneously) on the corresponding screen in each meeting-place; Show conflict if having, the replacement that then can cover perhaps, also can be judged earlier to have or not free screen (like the speech object of this broadcasting of the calling the roll screen of corresponding acquiescence not), if having, then preferentially replaces free screen, if do not have, then does covering replacement.Perhaps, if once only call the roll speech zone of broadcasting, its corresponding speech video can default main screen or all screen displays in each meeting-place.Perhaps; Can specify the corresponding relation of the display screen in the corresponding speech video in each request floor zone and each meeting-place by network side conference control equipment or Chair site terminal (according to user instruction or preset strategy); Each meeting-place shows the speech video of corresponding request floor zone correspondence according to the corresponding relation of appointment at the display screen of correspondence.Perhaps, the prioritization in request floor zone can be carried out in network side conference control equipment or Chair site terminal, and the order of prioritization can be corresponding with the screen number order, and prioritization preferentially shows at the speech video in preceding request floor zone.For example, corresponding single screen meeting-place, it can the regional speech video of a request floor that display priority is the highest.Certainly, the terminal, meeting-place of network side conference control equipment or Chair site also can be according to actual needs, and above display strategy is used in combination, or also can select other display strategy, enumerates no longer one by one here.

The embodiment of the invention also provides a kind of speech application method; Can comprise: obtain first meeting-place sign and first area sign; Wherein, This first meeting-place identifies pairing meeting-place and comprises a plurality of zones, and this first meeting-place identifies pairing meeting-place and belongs to first meeting, and this first area is designated the area identification that this first meeting-place identifies the request floor zone in the pairing meeting-place; Generate and send and carry the first area speaking request that first meeting-place sign and first area identify, so that after conference control equipment receives this first area speaking request; If confirm to allow this first area to identify corresponding request floor zone speech, then trigger and in first meeting, remove the regional corresponding speech video of the said request floor of meeting-place terminal broadcast that first meeting-place identifies pairing meeting other at least one meeting-place outside the venue.Wherein, above-mentioned speech application method can practical implementation on terminal, meeting-place or miscellaneous equipment.

Therefore; Pass through in the present embodiment meeting-place of meeting is divided into one or more zones, come request floor according to the zone in the conference process, when make a speech in the request floor zone in allowing certain meeting-place; Can in meeting, only broadcast the corresponding speech video in this application speech zone in the terminal, meeting-place in other at least one meeting-place; This treatment mechanism target of broadcasting of calling the roll that become more meticulous helps improving the flexibility of meeting speech, and owing to can only broadcast the corresponding speech video in request floor zone; So can reduce impact, help saving as far as possible bandwidth resources to the network bandwidth.

Embodiment two

For ease of better understanding the technical scheme of the embodiment of the invention, the process with a certain zone of a certain meeting-place of participating in a certain meeting (below be called meeting-place A) (below be called regional A01) request speech is that example is described in detail below.Main process with practical implementation in networking structure for example shown in Figure 3 is that example is described in the present embodiment.Wherein, for example the Chair site of this meeting is meeting-place B, and the terminal, meeting-place of meeting-place B is terminal, meeting-place b, and the terminal, meeting-place of meeting-place A is terminal, meeting-place a, and the terminal, meeting-place of meeting-place C is terminal, meeting-place c, and by that analogy, the terminal, meeting-place in each meeting-place possibly be one or more.

Referring to Fig. 4, concrete steps can comprise:

401, terminal, meeting-place a is to multipoint control unit MCU sending zone speaking request;

Under a kind of application scenarios; Carry out in the process in meeting; If the regional A01 among the A of meeting-place need ask speech; Then terminal, meeting-place a can be to MCU sending zone speaking request, and this zone speaking request can be carried the information such as sign in zone (regional A01) of meeting-place sign and the request floor among the A of this meeting-place in meeting-place (being meeting-place A) under this terminal, meeting-place, for example goes back quantity or the like the information in portability type of message, request floor zone; Certainly, the quantity in the zone of request floor also can be confirmed according to the number of the sign in the zone of the request floor that carries in the regional speaking request.

It is understandable that to have one or more participant to need speech in the zone of a request floor in the meeting-place, wherein also can not have the participant certainly, and possibly be need be in meeting one group of object showing of other meeting-place or scene etc.The zone of a request speech can be to the picture pick-up device (like video camera) of speech video that one or more these zones of seizure that can be real-time should be arranged.In practical application, can be based on the picture catching scope of each picture pick-up device in the meeting-place, carry out the zone to the meeting-place and divide, at this moment, the different zone in the meeting-place can be corresponding different picture pick-up devices, each zone in the meeting-place then can corresponding one road motion video.Therefore, can utilize video camera label, video code flow numbering etc. that each zone in the meeting-place is identified, be about to the sign as corresponding region in the meeting-place such as video camera label and/or video code flow numbering.

402, MCU receives the regional speaking request from terminal, meeting-place a, and transmit to the terminal, meeting-place (terminal, meeting-place b) of the Chair site (meeting-place B) of meeting should the zone speaking request.

In practical application, speech also can be asked in one or more zones in the one or more meeting-place of other in the meeting, and MCU also can receive the regional speaking request from other terminal, one or more meeting-place, and it is transmitted to terminal, the meeting-place b of Chair site B.And/or speech also can be asked in the one or more meeting-place of other in the meeting, and MCU also can receive the meeting-place speaking request from other terminal, one or more meeting-place, and it is transmitted to terminal, the meeting-place b of Chair site B.That is to say, but both support area speech applications, meeting-place speech application that also can compatible prior art.

403, terminal, the meeting-place b of Chair site B receives the regional speaking request that MCU transmits, and sends the meeting control command to MCU.

Wherein, above-mentioned meeting control command for example can be that many pictures are provided with the choosing of instruction, meeting-place and see instruction, zone are selected and see instruction, meeting-place roll-call broadcasting instructions, regional roll-call broadcasting instructions or the like.Terminal, the meeting-place b of meeting-place B can see the video image of preview speech object, the broadcast operation of calling the roll again after the preview through the choosing of many pictures, screen is set.

Under a kind of application scenarios; After the regional speaking request of the sign that receives the regional A01 that carries the request speech among the A of meeting-place that MCU transmits; If allow regional A01 speech, terminal, the meeting-place b of Chair site B can send the zone roll-call broadcasting instructions of roll-call broadcast area A01 to MCU.

In actual applications; Terminal, the meeting-place b of Chair site B can handle the regional speaking request that MCU forwards immediately, for example, if terminal, meeting-place b receives the regional speaking request of terminal, the meeting-place a of MCU forwarding; Then terminal, meeting-place b can or preset strategy according to user instruction; Determine whether to allow the regional A01 speech of the request speech among the A of meeting-place,, can send the zone roll-call broadcasting instructions of roll-call broadcast area A01 to MCU if allow; If do not allow, then can notify the A01 speech application failure of terminal, meeting-place b zone by MCU.

Perhaps; Terminal, the meeting-place b of Chair site B also can preserve the regional speaking request that MCU forwards earlier; And can further generate and safeguard a speech application tabulation (wherein can write down the sign of request floor object, for example the information such as sign in the zone of the sign in the meeting-place of request floor, request floor).At this moment; Terminal, the meeting-place b of Chair site B can or preset strategy according to user instruction; In speech application tabulation, select a request floor object (for example zone or the meeting-place) broadcasting of calling the roll (this sentences the regional A01 that has selected meeting-place A is example); Perhaps, also can select a plurality of request floor objects (for example zone and/or meeting-place) broadcasting of calling the roll (this sentences in zone and/or the meeting-place of selection and comprises that at least the scene of the regional A01 of meeting-place A is an example) simultaneously.

404, MCU receives the meeting control command from Chair site terminal b, and carries out the meeting control operation according to this meeting control command.

Wherein, If what MCU received is the roll-call broadcasting instructions of broadcast area A01 (sign that wherein can carrier area A01, also can further carry information such as type of message and display mode indication) from the meeting control operation instruction of terminal, the meeting-place b of Chair site B; MCU can confirm to allow the regional A01 speech of meeting-place A according to this roll-call broadcasting instructions; And the meeting-place terminal broadcast in other at least one meeting-place should be asked the corresponding speech video in speech zone in meeting, and the speech video of the on-screen display (osd) area A01 in its meeting-place is then controlled at the terminal, meeting-place in this other at least one meeting-place.

Under a kind of application scenarios; The speech video in this application speech zone or meeting-place can initiatively be sent to MCU in the terminal, meeting-place in each request floor zone or meeting-place, place, meeting-place; MCU handles its broadcasting of calling the roll accordingly when confirming to allow this application speech zone or meeting-place speech; Perhaps, the speech video in this application speech zone or meeting-place also can be sent again in the terminal, meeting-place in each request floor zone or meeting-place, place, meeting-place to MCU when being allowed speech by notice, and MCU handles its broadcasting of calling the roll accordingly.

In practical application; No matter the Chair site terminal is selected one or select the broadcasting of calling the roll of a plurality of request floors zone or meeting-place, the display position of the pairing speech video in request floor zone or meeting-place on the screen in each meeting-place that all can clearly called the roll and broadcast simultaneously.For instance; Each speech zone or the meeting-place default acquiescence of pairing speech video show (the main screen in the speech video correspondence multi-screen meeting-place that for example, the speech video correspondence of video camera 1 seizure shows at the screen 1 in each meeting-place, send at the terminal, meeting-place in single screen meeting-place or all screen displays etc.) on the corresponding screen in each meeting-place; If the conflict of demonstration is arranged, the replacement that then can cover, for example; The zone C 01 of regional A01 and the meeting-place C broadcasted meeting-place A if call the roll simultaneously, and regional A01 is identical at the default acquiescence display screen in each meeting-place with zone C 01 correspondence, then the broadcasting of calling the roll of one of them zone in the zone C 01 of regional A01 and meeting-place C of meeting-place A can be only selected at the terminal, meeting-place of MCU or Chair site; Perhaps; Also can judge earlier to have or not free screen (like the speech zone of this broadcasting of calling the roll or the meeting-place screen of corresponding acquiescence not),, then preferentially replace free screen if having; If no, then do the covering replacement.Perhaps, if once only call the roll broadcasting speech zone or meeting-place, its corresponding speech video can default main screen or all screen displays in each meeting-place.Or; Can also specify the corresponding relation of the display screen in the corresponding speech video in each request floor zone or meeting-place and each meeting-place by the terminal, meeting-place of Chair site (according to user instruction or preset strategy); Each meeting-place shows the speech video of corresponding request floor zone or meeting-place correspondence then according to the corresponding relation of appointment at the display screen of correspondence.Perhaps; The prioritization in request floor zone or meeting-place also can be carried out in MCU or Chair site terminal; The order of prioritization can be corresponding with the screen number order; Prioritization preferentially shows at the speech video in preceding request floor zone or meeting-place, the request floor zone that the less then common display priority in meeting-place of screen is higher or the speech video in meeting-place.For instance; This request floor zone or meeting-place prioritization of calling the roll broadcasting is followed successively by: the zone C 01 of the area B 01 of meeting-place B, the regional A02 of meeting-place A and meeting-place C; Then its corresponding speech video can be respectively in the screen 1 in each meeting-place, screen 2 and 3 corresponding demonstrations of screen; At this moment; If certain meeting-place has only two screens, then its can only at the corresponding speech video of the area B of its screen 1 demonstration meeting-place B 01, at the corresponding speech video of the regional A02 of its screen 2 demonstration meeting-place A, the zone C 01 pairing speech video of meeting-place C does not then show; If certain meeting-place has only a screen (promptly have only main screen), then it can only show on its main screen that the regional A02 of the speech video meeting-place A that the area B 01 of meeting-place B is corresponding and the zone C 01 pairing speech video of meeting-place C then do not show, by that analogy.Certainly, the terminal, meeting-place of MCU or Chair site also can be according to actual needs, and above display strategy is used in combination, perhaps also can select other display strategy to show control, enumerates no longer one by one here.

For example shown in Fig. 5-a; The request floor zone or the meeting number of record is a lot of in the current speaking application tabulation; For example region D 02 and the meeting-place J of area B 01, the meeting-place D of the meeting-place B wherein broadcasting of calling the roll is chosen at the Chair site terminal, and specifies its corresponding speech video respectively at screen 1, the screen 2 in three screen meeting-place with shield 3 and show; For two screen meeting-place, specify the screen 1 of screen 1 images displayed in two screen meeting-place in three screen meeting-place to show the screen 2 in the screen 2 corresponding two screen meeting-place in three screen meeting-place, therefore the speech video of two screen meeting-place viewing area B01 and region D 02 correspondence here; For single screen meeting-place, specify the video of screen 2 demonstrations in three screen meeting-place to show here in single screen meeting-place, therefore, single corresponding speech video of viewing area, meeting-place D02 that shields.

Special; The screen number that request floor zone of broadcasting if call the roll or meeting-place number have surpassed Chair site or other meeting-place; Then this meeting-place also can show the speech video in more called the roll broadcasting request floor zone or meeting-place, for example shown in Fig. 5-b with many pictures display mode.Wherein, can specify the speech video in concrete which request floor zone in each meeting-place or meeting-place to show, perhaps also can select at random by the terminal, meeting-place of Chair site or MCU with malti-screen.

Further; The regional A01 that request floor zone of broadcasting if call the roll or meeting-place comprise meeting-place A; In order to see request floor zone or panoramic picture that can field A01 place meeting-place A, MCU can also become the video-splicing of the All Ranges in meeting-place, regional A01 place a little picture be added to send to each meeting-place in the speech video of regional A01 and checks.

For example shown in Figure 6; For example the A meeting-place is deployed with 3 video cameras; It is trizonal images such as shooting area A01, regional A02, regional A03 respectively; Current region A01 request floor, MCU can be indicated the speech video of regional A01 is shown at screen 3, and each regional image mosaic that regional A01 belongs to meeting-place A become a little picture be added to regional A01 the speech video below.Further, can also can field information some of this meeting-place A, for example information such as meeting-place name is added on the speech video of regional A01, specifically can on the big image of the speech video of regional A01, superpose, also can be on spliced image or its near zone stack.

And the video that request floor zone of being broadcasted for calling the roll or meeting-place, place, meeting-place show can be the same with other meeting-place; Also can remain unchanged; Perhaps, also can not show the video in request floor zone or meeting-place, also can use a secondary picture to replace the image in request floor zone or meeting-place.

In addition, MCU also can handle called the roll the request floor zone of broadcasting or the audio frequency in meeting-place.For example for the multi-screen meeting-place; The zone that a video camera (perhaps one road motion video) is corresponding possibly be deployed with a plurality of sound pick up equipments (for example microphone) and put; These sound pick up equipments are tied to one group; The acoustic coding of this group sound pick up equipment becomes one road audio code stream, and a meeting-place has the MCVF multichannel voice frequency code stream, and the terminal, meeting-place can send to MCU respectively; Also can send to MCU to each synthetic one road audio code stream (like the AAC-LD dual track) of audio coding of organizing a plurality of different azimuth of sound pick up equipment, and can in this code stream, identify the audio code stream information of different azimuth.

The terminal, meeting-place of Chair site or MCU can also control under the speech zone of the broadcasting of being called the roll the sound in meeting-place and be broadcasted still that the sound in speech zone is broadcasted; If the sound in meeting-place, place is broadcasted, then the sound in the meeting-place, place, request floor zone of this broadcasting of being called the roll can be heard in each meeting-place in the meeting; If the sound in speech zone is broadcasted, then the sound in the request floor zone of this broadcasting of being called the roll can be heard in each meeting-place in the meeting, can not hear other regional sound of this meeting-place.These two kinds of broadcast modes can also can be provided with when conference setup in the MCU internal pre-configured, also can in meeting, pass through the signaling control modification in MCU turnkey console or chairman.

When calling the roll broadcasting a plurality of request floors zone or meeting-place simultaneously, MCU can send to each meeting-place behind the sound audio mixing with each speech zone or meeting-place (zone and/or meeting-place).

The sound that all speech zones or the meeting-place of the broadcasting of being called the roll can also be controlled in the Chair site terminal all is broadcast to whole meeting and listens; Still therefrom select the sound in one or several request floor zones or meeting-place to broadcast, can use regional roll-call broadcast control MCU complete operation.

Under a kind of application scenarios; The sound in the request floor zone of in meeting, being broadcasted calling the roll (or meeting-place, place sound) is when controlling; If need to control separately the audio frequency in request floor zone, the audio frequency control messages can be sent to MCU in terminal, chairman meeting-place, in this message portability operated the meeting-place sign, close the regional corresponding audio group number of sound (or playback), action type (closing sound or playback); Optional, go back the quantity that portability closes sound (or playback) zone) etc. information.MCU carries out Audio Processing based on audio frequency control message, if the indication playback is then broadcasted the regional sound of this speech to other meeting-place, if sound is closed in indication, then not to the regional sound of other meeting-place this speech of broadcasting.

Need to prove; The such scheme of present embodiment mainly is to describe in networking structure as shown in Figure 3, to be embodied as example, and it also can practical implementation in the networking structure that is deployed with meeting control and management platform certainly, for example can practical implementation in the networking structure shown in Fig. 7-a; Can manage and handle the relevant signaling of meeting by meeting control and management platform; The terminal, meeting-place in each meeting-place can be after meeting control and management platform sends speaking request (for example regional speaking request or meeting-place speaking request), and perhaps, speaking request (for example regional speaking request or meeting-place speaking request) can be sent to MCU in the terminal, meeting-place in each meeting-place; MCU is transmitted to meeting control and management platform with it; Meeting control and management platform then receives the meeting control commands such as speaking request in meeting-place, serve as chairman role and carry out request floor management and meeting control operation, and MCU carries out the zone Media Streams processing such as the broadcasting or the broadcasting of calling the roll of calling the roll and operates under the control of meeting control and management platform; Understandable thing; Under this scene, can there be Chair site in the meeting, if there is Chair site; MCU or meeting control and management platform also can be transmitted to the Chair site terminal with the meeting control commands such as speaking request in meeting-place, carry out corresponding meeting control operation by the Chair site terminal.Similar with it, such scheme also can practical implementation in the networking that is deployed with meeting control and management platform and medium processing device (for example IP multimedia subsystem, IMS networking structure), for example can practical implementation in the networking structure shown in Fig. 7-b; Under this networking; MCU can be equivalent to the medium processing device here, and each terminal, meeting-place of meeting neutralization can only mutual Media Stream, and each meeting-place then can directly send to meeting control and management platform (business platform) to the control signaling of meeting; Meeting control and management platform serves as chairman role and carries out request floor management and meeting control operation; Medium processing device then can carry out Media Streams processing such as a zone roll-call broadcasting or a roll-call broadcasting under the control of meeting control and management platform operates, and is appreciated that under this scene; Can there be Chair site in the meeting; If there is Chair site, meeting control and management platform also can be transmitted to the Chair site terminal with the meeting control commands such as speaking request in meeting-place, carries out corresponding meeting control operation by the Chair site terminal.Concrete process and Fig. 3 that realizes is similar at the networking structure shown in for example Fig. 7-a or Fig. 7-b, repeats no more here.Special; Corresponding existing meeting control and management platform; The scene that Chair site is also arranged; Meeting control and management platform also can be transmitted to the Chair site terminal with the relevant signaling of meeting from each terminal, meeting-place; By managing jointly with the control and management platform and handle the relevant signaling of meeting in Chair site terminal (end side conference control equipment) or Chair site terminal, and medium processing device or MCU can carry out the zone Media Streams processing such as the broadcasting or the broadcasting of calling the roll of calling the roll and operate under the triggering at Chair site terminal (for example specifically can directly or pass through meeting control and management platform etc. trigger indirectly).
